Liberal leader Mohamed ElBaradei has been chosen as Egypt's new prime minister, the Tamarod campaign behind protests that toppled Islamist president Mohamed Morsi said on Saturday after talks with the country's interim president.
A military source confirmed to AFP that the former head of the UN's International Atomic Energy Agency (IAEA) was to be sworn in as premier later on Saturday, three days after the army overthrew Morsi.
The official MENA news agency said ElBaradei was in talks with interim president Adly Mansour.
Tamarod, Arabic for Rebellion, had nominated ElBaradei to represent the grassroots movement in transitional negotiations with the military.
ElBaradei, who won the Nobel peace prize in 2005 for his work with the IAEA, returned to Egypt in 2010 and became a prominent opponent of veteran strongman Hosni Mubarak in the lead-up to the 2011 uprising that overthrew him.
Aya Hosni, a member of Tamarod's central committee, told AFP that "the interim president and Tamarod had agreed on Mohamed ElBaradei's nomination as prime minister".
She said former interior minister Ahmed Gamal El-Din would be in charge of security affairs and economist Ahmed al-Naggar would be the new finance minister.
On Wednesday, army chief General Abdel Fattah al-Sisi had outlined the roadmap for the transition, which included suspending the constitution and forming a government of technocrats before preparing for parliamentary and presidential elections.
